40d:Economic stone
Jump to navigation

Economic stones have special uses as ore, fuel or flux, or other uses like making special items. You can use the z : Stone menu to restrict or un-restrict their use in items and buildings. In technical terms, an economic stone is any stone which can be used as a reagent in any form of reaction. Obsidian is an exception, having been made an economic stonev0.28.181.40d even though it is not used in any reaction - its specialty is that it can be used to craft swords.
The Stone menu will also show what each stone can be used for--very useful for figuring out what you need to mine to make that obscure metal your noble is whining about.
